Just bought a new laptop (Lenovo Y520), I want to experiment in overclocking to see if I get any performance upgrade. I bought this laptop for gaming, I understand this is not exactly a top gaming laptop but I just want it for casual use.http://prntscr.com/kcqab9

I just watched a video on YouTube featuring guys for here talking about how to overclock with Intel Extreme Tuning Utility. From the video it looks like Lenovo have locked many overclocking features for some reason so there is very limited things I can do with it.

I have done benchmark tests with this with the 1st one taken without any overclock, 2nd with a 1V increase on Core Voltage and the 3rd with a 1.5V increase.http://prntscr.com/kcq6yiAs you can see that I did get a small increase in frequency from normal to a 1V increase but the overall score was lower, the 3rd seemed to lower the frequency and score dramatically!

I also would like help with overclocking the GPU, I have installed MSI Afterburner. Again they have limited the functions only alowing core and memory clock to be adjusted.
